In order to dissipate heat conveniently, a heat dissipation hole 651 is opened on the top of the heat dissipation cover, and the heat dissipation hole is a circular hole. The heat dissipation holes are used to dissipate heat from the heat dissipation chassis.

For example, the heat dissipation holes are opened on the top of the heat dissipation cover. The box body is rectangular and installed on the outer cylinder. For example, a receiving space 614 is formed in the box, and the heat dissipation base is disposed in the receiving space. Under the pull of the tension spring, the heat dissipation cover closes the receiving space, and at the same time, the exposed recess is misaligned with the airflow hole, so that the heat dissipation cover is used to close the airflow hole, and the heat dissipation cover The cooling holes are also sealed to keep out dust and moisture.

For example, the heat dissipation base is rectangular and protrudes from the box. For example, the heat dissipation base is integrally formed with the box body. The periphery of the heat dissipation base is spaced from the box, and a mounting slot is formed between the heat dissipation base and the box, and the mounting slot is used for heat dissipation and circulation. For example, multiple heat dissipation channels 6121 are opened on the heat dissipation base, and the diameters of the multiple heat dissipation channels are set differently. The heat dissipation channel extends along the length direction of the heat dissipation base and passes through the side wall of the heat dissipation base. The heat dissipation channel communicates with the airflow hole through the installation slot. When the airflow hole is opened, the heat dissipation channel can carry the heat in the heat dissipation base and export it to the outside through the airflow hole.

When the rotating lamp is energized, the temperature of the support sheet increases due to heat conduction, thereby elastically deforming, for example, the support sheet stretches and lifts the heat dissipation cover, so that the heat dissipation cover overcomes the tension of the tension spring and Gradually move away from the box body, so that the exposed recess is aligned with the airflow hole, so that the airflow hole communicates with the outside atmosphere. For example, the support sheet includes a base body and an extension tip disposed on the base body, the base body is fixed on the box body, the extension tip is in the shape of a thin sheet, and bends and extends, and the extension tip abut against the bottom of the heat dissipation cover. For example, the extension tip is connected to the bottom of the heat dissipation cover.

For example, in order to close the heat dissipation hole when the air flow hole is closed, an overflow hole is opened in the middle of the heat dissipation base, and a closing column 64 is protruded from the bottom of the box body, and the closing column is protruded on the The overflow hole protrudes to the top of the heat dissipation base, and a diversion gap is formed between the closing column and the side wall of the overflow hole, and the diversion gap penetrates the heat dissipation base. For example, the overflow hole is in communication with a plurality of the heat dissipation channels, so that the airflow can generate turbulent flow in multiple directions. For example, the closed column includes a support body 641 and a closed body 642. The support body is conical and protrudes from the bottom surface of the receiving space. The closure body is cylindrical and formed on the bottom surface of the support body. top. For example, the sealing body is exposed on the top surface of the heat dissipation base. The sealing body protrudes from the cooling hole. The diameter of the sealing body is equal to the diameter of the cooling hole. When the side wall of the heat dissipation cover closes the two airflow holes, the sealing body closes the heat dissipation holes, so that the heat dissipation mechanism forms a completely closed state, isolating the flow of air inside and outside, thereby avoiding dust Or moisture intrudes into the accommodation space of the box body, so as to prevent dust and moisture. And when the heat dissipation base is heated, the support piece can push the heat dissipation cover to move, the side wall of the heat dissipation cover can expose the airflow holes on the box body, and the closing body of the closed column can expose The heat dissipation holes on the heat dissipation cover can allow air to enter the accommodation space from the heat dissipation holes, then pass through the overflow holes, enter the plurality of heat dissipation channels of the heat dissipation base, and finally carry the heat dissipation The heat of the base body flows out from the airflow holes of the box body, thereby improving the heat dissipation efficiency of the bulk device. And when the heat dissipation mechanism cools down, the supporting sheet returns to its original shape and shrinks due to the characteristics of memory alloy. At this time, the two tension springs pull the heat dissipation cover to close on the box body. At this time, the two airflow holes are closed by the side walls of the heat dissipation cover, and the heat dissipation cover on the heat dissipation cover The heat dissipation hole is closed by the closing column in the box body, so that the heat dissipation mechanism can prevent dust and moisture.

For example, in order to improve the heat dissipation effect of the heat dissipation mechanism, a plurality of auxiliary heat dissipation holes 6122 are opened on the top surface of the heat dissipation base, and the plurality of auxiliary heat dissipation holes communicate with the plurality of heat dissipation channels. For example, the heat dissipation auxiliary hole penetrates through the heat dissipation base. The extension direction of the heat dissipation auxiliary holes is perpendicular to the extension direction of the heat dissipation channels, so that the cold air introduced in the heat dissipation holes is conveniently introduced into the plurality of heat dissipation channels. For example, in order to increase the guiding effect so that the cold air can smoothly enter the plurality of heat dissipation auxiliary holes, a plurality of guide fins are also arranged on the heat dissipation base, and the plurality of guide fins are arranged at intervals from each other. The guide fins are disposed on the peripheral edge of the heat dissipation auxiliary hole and extend obliquely toward the heat dissipation hole. A guiding arc surface is formed on the guiding fins. Since the guide arc extends obliquely toward the heat dissipation hole, it can smoothly guide the heat in the heat dissipation hole so that cold air enters the heat dissipation auxiliary hole. At the same time, due to the arrangement of the guide fins, the cold air can be used to cool the guide fins during the process of guiding the cold air to assist in heat dissipation, thereby improving the heat dissipation effect of the heat dissipation mechanism. For example, in order to prevent the lateral flow of cold air, a plurality of communication holes are opened on the guide vane, and the plurality of communication holes pass through the guide vane. For example, in order to avoid the blocking effect of the guide fins on the heat dissipation cover, so that the heat dissipation cover can be smoothly covered on the box body, the top of the guide fins is spaced from the heat dissipation cover, Therefore, a space is left, so that the closing column can be closed in the heat dissipation hole of the heat dissipation cover. For example, the heat dissipation base is also provided with a plurality of air induction holes, the plurality of air induction holes are opened on the side wall of the heat dissipation base, and the extension direction of the air induction holes is in line with the extension direction of the heat dissipation channel. vertical. Through the setting of the air-introducing holes, heat dissipation channels and the auxiliary heat dissipation holes, the mass of the heat dissipation base can be reduced, and the contact area between the heat dissipation base and air can be increased, that is, the heat dissipation area of the heat dissipation base can be increased. , thereby improving the cooling efficiency.

For example, in order to prevent the heat dissipation cover from being easily opened, a plurality of guide fins protrude from the side wall of the box, and the guide fins are made of memory alloy. The guide piece is arranged between the side wall of the heat dissipation cover and the side wall of the box body to increase the friction between the heat dissipation cover and the box body to ensure the sealing of the heat dissipation mechanism performance. For example, the guide sheet extends obliquely relative to the side wall of the box. When the guide piece is heated, it can stretch and be flatly attached to the side wall of the box body, so that the support piece can lift the heat dissipation cover, so that the heat dissipation cover is opposite to the box. body moves. When the device cools down, the guide piece can return to its original shape and extend laterally, abutting between the side wall of the heat dissipation cover and the side wall of the box body, increasing the distance between the side wall of the heat dissipation cover and the side wall of the box body. The frictional force between the side walls of the box body prevents the heat dissipation cover from being opened arbitrarily. For example, a passage hole is opened on the guide sheet, and the passage hole communicates with the airflow hole of the box body correspondingly. When the support sheet supports the heat dissipation cover, the guide sheet is stretched and attached to the box body. At this time, the airflow hole, the passage hole and the exposed depression are connected to each other, and there is Conducive to the outflow of hot air. And when the supporting sheet returns to its original shape, the side wall of the heat dissipation cover blocks the airflow hole, and at the same time, the guide sheet body returns to its original shape and bends, so that the passage hole and the airflow hole are misaligned, thereby blocking the airflow hole. The airflow hole, while the exposed depression is also misaligned relative to the airflow hole.

The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, should be considered as within the scope of this specification.
